Timing Diagram
AC FE E DT HROUGH E RROR
T his is the error caused by capacitance coupling from V
REF
to
the DAC output with all switches off.
SE T T LING T IME
Settling T ime is the time required for the output function of the
DAC to settle to within 1/2 LSB for a given digital input signal.
PROPAGAT ION DE LAY
T his is a measure of the internal delays of the DAC. It is defined
as the time from a digital input change to the analog output cur-
rent reaching 90% of its final value.
CHANNE L-T O-CHANNE L ISOLAT ION
T his is the portion of input signal that appears at the output of a
DAC from another DAC’s reference input. It is expressed as a
ratio in dB.
DIGIT AL CROSST ALK
Digital Crosstalk is the glitch energy transferred to the output of
one DAC due to a change in digital input code from other
DACs. It is specified in nVs.
PARAME T E R DE FINIT IONS
RE SOLUT ION
Resolution is the number of states (2
n
) that the full-scale range
(FSR) of a DAC is divided (or resolved) into.
NONLINE ARIT Y
Nonlinearity (Relative Accuracy) is a measure of the maximum
deviation from a straight line passing through the end-points of
the DAC transfer function. It is measured after adjusting for
ideal zero and full-scale and is expressed in LSB, %, or ppm of
full-scale range.
DIFFE RE NT IAL NONLINE ARIT Y
Differential Nonlinearity is the worst case deviation of any adja-
cent analog outputs from the ideal 1 LSB step size. A specified
differential nonlinearity of
±
1 LSB maximum over the operating
temperature range ensures monotonicity.
GAIN E RROR
Gain Error (full-scale error) is a measure of the output error be-
tween the ideal and actual DAC output. T he ideal full-scale
output is V
REF
–1 LSB.
OUT PUT CAPACIT ANCE
Output Capacitance is that capacitance between I

, I

and AGND.
